target & lib?

• target
  • 빌드의 결과물을 어떤 버전으로 할 것이냐
  • 지정을 안하면 es3
• lib
  • 기본 type definition 라이브러리를 어떤 것을 사용할 것이냐
  • lib 를 지정하지 않았을 때,
    • target 이 ‘es3’ 이고, default 로 lib.d.ts 를 사용
    • target 이 ‘es5’ 이면, default 로 dom, es5, scripthost 를 사용
    • target 이 ‘es6’ 이면, default 로 dom, es6, dom.iterable, scripthost 를 사용
  • lib 를 지정하면 그 lib 배열로만 라이브러리를 사용
    • 빈 [ ] ⇒ “no definition found ~~”
